Targeted server upgrade

This 32GB DDR4 ECC registered DIMM is built for Lenovo Converged Appliance models HX3510-G, HX3710, HX3710-F, HX5510 and HX5510-C. It replaces Lenovo part numbers 46W0832, 46W0833, 46W0835, 4X70G88320 and 4X70M09263. The module runs at 2400MHz with CL17 latency at 1.2V. It is not compatible with standard desktop computers.

Build integration

The 288-pin registered design requires a server or workstation motherboard that supports ECC RDIMM memory. It cannot be mixed with unbuffered modules in the same system. Installing this kit adds error-correcting capacity to the listed appliances without needing additional cooling hardware. The single-module layout leaves remaining slots free for further expansion.

Upgrade context

This part suits administrators extending the life of existing HX-series appliances or building cost-effective replacements. It does not serve buyers who need unbuffered memory for consumer platforms or who require higher-speed grades beyond DDR4-2400. The jump is worthwhile when the target system specifies PC4-19200 registered ECC and the current configuration has available DIMM slots.

Questions about this item

What is the CAS latency of this DDR4 2400MHz module under sustained server workloads?

The module runs at CL17 latency at its rated DDR4 2400MHz speed.

How much power does the 1.2V registered DIMM draw when the appliance runs continuously?

It operates at the standard DDR4 1.2V voltage; registered ECC modules typically draw slightly more power than unbuffered DIMMs due to the register.

Which Lenovo Converged Appliance models must I already own for this 288-pin RDIMM to work?

Compatible systems are the HX3510-G, HX3710, HX3710-F, HX5510 and HX5510-C.
